To all whom it may concern:

Be it known that I, WILLIAM H. Goon, a citizen of the United States, residing at Greensburg, in the county of Westmoreland and State of Pennsylvania, have invented a certain new and useful Composition for the Manufacture of Artificial Stone, of which the following is a specification.

This invention relates to the art of making artificial stone and the like, and has for its object to provide a composition of material which is simple, practical, and which can be produced at a low cost.

A further object of the invention is to provide a composition which will produce a material having great hardness and strength combined with fire and moisture resisting pro erties; which wi pro uce a. a much shorter time than by the use of the mixtures heretofore used, and which can be put up in a convenfor storage, shipment and use.

A further object of the invention is to have the ingredients so combined that the desired results can be obtained by those desiring to use it without any previous knowl edge of the art.

The composition consists of the following ingredients combined in the proportions hereinafter stated: forty-eight parts by measure of sharp, clean sand eighteen parts by measure of cement we ve parts by measure of fire-clay and one part by measure of rock-sa In the manufacture of the compound it is important to first have all of the materials well mixed together with the exception of the rock-salt, to accomplish which purpose the fire-clay should be well pulverized so that it will mix with the sand and cement. A sufficient quantity of water in which the rock-salt has been dissolved should then be added to form a plastic mass. The mixture is then placed in a mold or forms, tampered li htly and left to set and dr In a short time the removed and no further wetting down of the material is necessary. I have found that the use of the ingredients in the exact proportions stated gives results which are not otherwise secured; that the material or stone thus formed sets and dries with great rapidity, and that the same is impervious to moisture, and combines great hardness with strength.

Having thus described my invention what I 'claim as new and desire to secure by Letters Patent is:

A composition for making artificial stone and the like consisting by measure of 48 parts of sharp sand, 18 parts of cement, 12 parts of fire-clay and 1 part of rock-salt combined as herein stated.

- WILLIAM H. GOOD.
